Build up your feline friend's confidence and natural instincts - their "cat-mojo" - with Jackson Galaxy Base Camp Hub Combo. It's an amazing cat playground and superhighway for fun, plus a safe haven. Comes with a solid green nylon tunnel that zips on to the Hub to encourage stalking and exploration, with additional zippered portals to add more Cat Crawl tunnels in either mesh or solid nylon styles. Catify their environment and you can "paws-itively" influence your cat's well-being!
